Answer:

y = \frac{49}{3}

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 7 when x = 3

k = \frac{y}{x} = \frac{7}{3}, thus

y = \frac{7}{3} x ← equation of variation

When x = 7, then

y = \frac{7}{3} × 7 = \frac{49}{3}

noname [10]

Answer: B). 38:inches

Step-by-step explanation: the two length 20 and 28 have a close range of value. So the next close range of value is the 38 inch which will make a perfect fit.

Note this rule is by trial and error method and no formula is behind it.

Answer:

c) The growth factor per days is 1.08

e) The growth factor per hour is 1.08^{1/24}

Step-by-step explanation:

Given the following data;

P(d) = 10 * 1.08^{d} in thousands.

a. To find the number of insects on day 1;

Day, d = 1

P(d) = 10 * 1.08^{d} ......equation 1

Substituting into the formula, we have;

P(1) = 10 * 1.08^{1}

P(1) = 10 * 1.08

P(1) = 10.08

Therefore, option (a) and (b) are incorrect.

c. To find the growth factor per day;

An exponential function is given by the formula;

y = mg^{x} .....equation 2

Where;

g is the growth factor of a population.

Comparing eqn 2 with eqn 1;

g = 1.08

Therefore, option (c) is correct.

e. To find growth factor per hour;

From equation 1 above;

P(1) = 10 * 1.08^{\frac {1}{2}}

Therefore, option e is correct.
